Integrating with Interchange

Express checkout transactions must be used with normal card processing as part of the PayPal merchant agreement (see the PayPal Integration guide for rules on placement and operation). This is treated as a separate payment method, with its own unique entry in order.profile. The UserTag paypal_api.tag communicates with the PayPal API to set the transaction parameters and read responses. The file payment.html can be used for this.

Configuration & Testing

Download the files (at left) and install PaypalPro.pm in lib/Vend/Payment directory, and paypal_api.tag in the global usertag directory.

Reqest a PayPal certificate, if you have not already. Also, under “Website Payment Preferences” for your PayPal account, ensure the contact telephone number is required.

Copy the PayPal SSL certificates into a directory readable by the user that runs Interchange, such as /var/lib/interchange

It’s appropriate time to make some plans for the future and it is time to be happy.
